with which I am unacquainted, no specimen having been left 

 by him. 



The Tern, is Adicmtiun Caudatum, a wide spread Fern found 

 in Mauritius and most other Islands of the Mascarene group. 

 I may however remark in passing that its habit at Eound 

 Island is so much changed, especially in the young stage, that 

 I could scarcely at first recognize it. 



Turning next to the flowering Plants and commencing'with 

 the Monocotyledons or those having one-lobed seeds, we 

 have five grasses composing the scanty herbage of the Islet. 

 Strange to say that which is most common, growing in tufts 

 among the Trees at the Summit, appears identical with the 

 Indian " Citronelle " or Lemon grass " Andro]pogon " or 

 " Gt/mhojpogon ScTwenantlms " of Bojer, who however distinctly 

 states it not to be a native of Mauritius, nor can it even to 

 this day be said to be naturalized here ; unluckily the speci- 

 mens brought away have been lost. The next grass, N"o. 5 of 

 Mr. Home is not to be found in the Eoyal College Herbarium, 

 and it is supposed by him to be new. 



The third— numbered 7, is the " Gynodon " mentioned by 

 Colonel Pike, and we all, judging from its mode of growth, 

 referred it to that genus, but it will be seen to differ totally 

 from the GMen Dent, or JPetit Chien Dent, so common here. 

 Of Mr. Home's number 8 only a single imperfect specimen 

 was obtained, which has been sent to Dr. Hooker at Kew, 

 unidentified with any in the Herbarium. 



The single Sedge, on the other hand, appears to be " Cy- 

 perus maritimus " common to Mauritius. 



We come now to the more interesting Tribe of the Yacoas 

 — of which Round Island certainly possesses one peculiar to 

 itself and very distinct from any of the sixteen specimens 

 enumerated by Bojer who seems never to have seen it. It is 

 said to have received the name of " Fandanus Vandermeerschii '* 

 in Europe after the present intelligent Lessee of the Islet, 

 by whom it was some time since sent home to the Botanic 

 Garden at G-hent. I have not however met with a description 

 of it in any botanical work. 



In general habit it is not unlike the common Vacoa from
